5.1 Selecting the Mounting Location
Fire hazard due to wrong choice of mounting location
Despite careful construction, electrical devices can cause fires.
• Do not mount the DC sub-distribution on flammable construction materials.
• Do not mount the DC sub-distribution in areas containing highly flammable materials.
• Do not mount the DC sub-distribution in potentially explosive atmospheres.
Requirements for the mounting location:
☐ The mounting location can be outdoors or indoors.
☐ The mounting location must not be in a living or office area.
☐ The mounting location must not block any escape routes.
☐ The mounting location must be freely and safely accessible at all times without the necessity for
any auxiliary equipment (e.g. scaffolding or lifting platforms). Non-fulfillment of these criteria
may restrict servicing.
☐ The mounting location must be shaded, e.g. under a protective roof.
☐ The mounting location must be suitable for the weight and dimensions of the SMA
Sunny String‑Monitor.
☐ The mounting location must be suitable for the wind load.
☐ Mounting space below the SMA String Monitor when using the inline fuse connectors:
at least 800 mm.
Requirements for mounting the SMA String-Monitor
☐ Mount the SMA Sunny String-Monitor so that the connection area is facing downwards.
☐ Mount the SMA String-Monitor in a horizontal position.
☐ Do not mount the SMA String Monitor in a twisted manner.
☐ Do not mount the SMA Sunny String‑Monitor in a horizontal or inclined position.
☐ An external cable support rail must be provided.
Example: Mounting on PV array substructure
• If the PV array is mounted on a free-standing
structure, the DC subdistribution can be fixed to
this structure in a shaded position. In this case,
make sure that there is no danger of rainwater
flowing off the module surface and over the
enclosure of the DC subdistribution.
